Hello all folks ..

Have a frind down here making a big toy with 44" TSL 2.5 ton axles, truck ( pegasusus or something like ) tranny and 6BT ..

the question that he made to me is .. there are R&P options for those rockewells .. ?

thought are pretty factory short .. like 6.** or so ..
 
Randy has been working on new gear ratios for the 2.5 ton axles, but as it stands, there are not many options right now.

thanks Mace ..

But they dono't have R&P options .. looks like not much people need it ..
 
Like I said, they are in the works..

And no, by the time you go rockwells, gear ratios are not that big of a deal..

you need BIG horsepower to spin those imho

why?

the 6.something gear ratio makes them easier to spin than a Toy axle..
 
6.72 I THINK are deep eeee nuf. I got a set of steer axls for sale. 1 is new the other is used but has a new detroit $ 1200.00 By the way ther in the twin citys ( MN ) and I DO NOT DELIVER
 
lots of guys here running rockwells with much larger tires and no issues.we run timken axles in our mud trucks with 6.17s and 50"military tires.350 chevy bus engine and 400r4 with no problems .my 40 has timken axles 501 caddy 400 auto and 11.24 tractor tires and it spins them fine.check out yankey lake dot com and see some of these trucks work good luck
 
6.72's is a great gear for a 44" tire.. You're not gonna be doing 80 down the highway with a rig on rockwells, so why fart around worrying about lower gears?

65mph with 44's is 3300RPM in 1:1. if you have an OD trans and the torque to push it.. it'll be about 2300RPM. How is that not perfect? Any V8 can turn 3300 all day long, and if you're running a diesel, just make sure you have an OD trans if you want highway speeds.

I don't have BIG HP (about 330), but have little problems getting them spinning, as anyone who's seen me wheel can attest.
 
330 is pretty healthy.....i'd like to see a 4 banger or toyota diesel spin 44's fast enough to clean them and propel those heavy ass axles up something steep and slick.....and how much would a LC weigh with rocks?

Buddy of mine had Convertiyota's old buggy, and it had a 22RE with Rocks and 44's.. it spun them up OK, but it was very light weight.

A 40 with rocks would weigh about 1100lbs more than stock, plus the additional weight of heavier tires & wheels... but the gearing does take quite a bit of stress off the driveline components, which is a good thing.

that probably works awesome out west where you have great traction all the time

I am not going to get into the East Vs West debate right now.

The rockwell is not the major issue if you have to spin the crap out of your tires.. It is the size of the tires.. Not the axle.

A ford 9" with a 6.5:1 ratio behind a suzuki motor and 44's would have the same problems spinning a tire as a rockwell with the same motor and tires..


It is the axle's fault for HP. It is more of hte owners driving habits that require a larger axle to deal with hp and wheeling conditions.
 
Portal hubs are available for rockwells.

that's key right there obviously.....but i think he is talking about a 60 or 80 series? and i know yall have seen the sloppy goo that Tapage wheels in....

but you almost have to run big tire with rocks BEcause of the super low gearing, that's the point, you aren't restricted like that with any other axle and if your trapped with those super low gears in your axles and your in the mud or on steep slick hills then you need to be able to shift up and lay the by God wood..... if you had a ford 9" with those gears you'd prolly break it getting off the trailer

i have a friend that has a REally heavy (7400 lbs.) fullsize rig on rocks and 47's with a built 318 out of a dragcar and when it's wet and muddy he can't get up hardly anything...i love riding with him though because he makes my 40 look like a ultralight buggy in comparison lol

Thanks for all comments fellas ..

Mate it's running a big 2500 frame and body .. with a heavy 6BT that no go over 2600 rpm or so .. but torque, no clue but that's the main reason for new longer R&P search ..

I would recomend 49" Irocs .. :D

But he love the TSL performance ..

If you want to cruiser highway speeds then yes, but the lower powered rigs are gearing down their tcases lower than that just for the power. It jsut depends on if you want your gear ratio in the tcase or in the axles. THe only reason mini's are not running anything lower than a 5.27 (IIRC is the lowest) is becasue of carrier and strength issues..

Will you have mud slinging power??

No you won't, but you would not have that with a 33" tire and no gearing either if you think about it.

The low gear ratio is handy for a alot of reasons. It's just that most people do not want rockwells due to the weight of the axles themselves.

Motor and wheeling conditions warrant big axles, the axles themselves do not define what motor you are running..


And, you are pretty far off base on the 9".

your right, those 9's are damn strong....

lol

what's weak about them?

Comp guys are running 40 spline 9" axles all the time and having good results with little breakage. It all depends on price.

They are far from weak.

Donno that I would run 49" tires on one. But hell, even the 2.5 ton junk is not holding up to tires that big (shafts, ring and pinions etc..).

Rockwells are cool because they are fairly good when it comes to strength and cost.

kinda like a 14 bolt. $100 gets you to 44" tires easily.
